Please help! I first thought my lab-X suffered from separation anxiety due to constant destruction, even though he was always with the other dog. That seems to have stopped. Then he kept "digging" at his ears -- I bought him ear mite drops. That stopped "temporarily". Now he continually stratches, has dandruff, dry skin and several "large" bald spots, and is losing still more hair. He also seems to have an ear irritation, because he keeps shaking his ears. Oh, and his coat has a mild odour to it. HELP!
